Zoom on the Cat INV1250
In a nutshell, the Cat INV1250 is a quiet, compact and lightweight portable inverter generator mostly geared towards:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- Amateur DIY lovers
Power & Run Time
The Cat INV1250 is powered by a 60 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1000W as well as a peak wattage of 1250W. Moreover, since it is parallel capable (parallel kit not included), its power may be doubled if linked to a second compatible unit.
At a noise rating of 52 dBA (just slightly more noisy than a quiet suburb), the inverter generator is started via a conventional pull-start mechanism.
The fuel capacity of 0.8 gallon allows the INV1250 to operate for around 7.9 hours at 50% load with a full tank (fuel consumption around 0.1 GPH).
The INV1250 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlet safely.
The control panel features the following AC outlet:
Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.
The Cat INV1250 is an inverter generator and has an encased design of the following dimensions: L18.3 x W11.5 x H16.6 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.
The INV1250 is a lightweight, portable generator, as it only weighs 33.1 lbs. A single person should not have any problems moving it around and thus, enjoy power availability on-the-go. It can also be carried without effort with a featured handle (molded in the case), further improving its convenience.
The light indicators show you if the generator is ready, the generator is overloaded and its oil levels are insufficient.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
The INV1250 also benefits from CAT’s CO DEFENSE™ carbon monoxide shutdown. This system monitors the accumulation of CO gas while the generator is running and will shut off the engine if the levels become dangerously high. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Cat INV1250's package also includes these accessories: oil, funnel and tool kit.
The Cat INV1250 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
The Cat INV1250 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Cat INV1250 compare to generators of similar power (between 1000 and 2000 W).
- As for its weight, the Cat INV1250 weighs only 33.1 pounds, making it one of the lighter generators in the 1000-2000 rated wattage category. In terms of weight, one of the champions in their power range is the Genmax GM1200i, standing at just 25.3 lbs.
- With a lowest noise rating of 52 dBA, the inverter generator is one of the more quiet of the generators of similar power. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
- Offering around 7.9 hours of running time on a full tank at 50% load, the INV1250 is within the average autonomy range of similarly powerful generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Pulsar PG2200, which is able to run for around 12 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. At an estimated fuel consumption of 0.1 GPH (gallon per hour) at 50% load, this inverter generator is one of the most fuel efficient units within its wattage category.
